[dpdk-dev] [PATCH] net/mlx5: fix CRC strip cap query

[Shahaf Shuler]

IBV_WQ_FLAGS_SCATTER_FCS is a WQ flag to be used to configure the CRC
strip on a queue upon creation.

Using IBV_RAW_PACKET_CAP_SCATTER_FCS instead to query to capability.
Even though this is RAW_QP capability, it is being used by rdma-core to
indicate for both RAW_QP and WQ.

Fixes: 43e9d9794cde ("net/mlx5: support upstream rdma-core")
